LOCOMOTIVE-CAB TURRET.

Application filed September My invention relates to an improved construotion of locomotive cab and turret, and

contemplates forming the front wall of the "turret, the turret serving as closure for the opening.

It has been the practice, heretofore, to por inanently secure the front wall of sheet metal cabs, to the side walls and roof, by rivets, and to form a number-of holes through the central portion on the front wall, for the passage of the various pipes, valves, and valve stems leading to the turret, which is disposed on the top of the boiler, away from the front wall. This practice is seriously obs jectionable, in that the holes soon become enlarged to an extent permitting undesirable currentsof air to enter the cab. A further objection is that all of the connections-leading to the turret must be disconnected therefrom, whenever the cab is removed for repairs. and re-connected when thecab is again installed. This latter difficulty involves a 7 material loss in :time and labor.

An object of the present invention,-accordingly, is to provide an improved construction of front wall andturret, whereby the various disadvantages noted in connection with cab front wall and turret construction, heretoforeknown, are completely eliminatcd.

The improvement clalmed 1s hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a side View, in elevation, of the upper part of the rear end of a locomotive, with a portion of the front of the cab broken away, to show the connection between the front wall and'turret; Fig. 2, a plan View, in section, on an enlarged scale, through the, cen tral portion of the front wall of, the cab, showing its connection to the boiler andturret; Fig.3, atransvcrse section through the upper part of the cab, showing the manner of attachment ofthe front wall, to the boiler and turret; and, Fig. 4:, an enlarged section 'ofthe front wall of the cab and the upper rear end of the boiler, showing thedetails of the detachable connection between thefront wall and the turret.

In the practice of my invention, referring descriptively to the specific embodiment thereof which is herein exemplified, the construction comprises a boiler, A, to which is 2a, 1925. Serial No. 137,225.

.walls, 11, and a front wall. C, all made of sheet metal. The front wall comprises two side sections, 12, each being of a- Width to accommodate the windows, 12*, and a centre section, 12 which is substantially arch shape, and is detachably secured at eachpof its opposite ends, to one of the side sections, by the welt strips, 12; Eaclrwelt strip is permanently secured to the sidesection by rivets, 12 and detachably secured to the centre section by bolts, 12. i

To permit passage through the front wall of the various valve bodies, 13, and stems, 14, lcadino; to the turret, there is provided centrally of the centre section, an elongated opening, 13 In order to provide for closingthe opening. 13, the turret, D, is formed,

turret together.

The rear wall, 15, of the manifold, is provided with opemngsinto some of which are tapped' -the valve bodies, 13, and th ough some of which pass the valve stems, 14.

The front wall, 15", of the manifold, is pro-,

videdwith openings, into which are fitted the valve seats, 16. The valve seat openings are disposed in axial alignment with the valve stem openings, in the rear wall,f15, of the manifold. c

Fort-he purpose of giving a strong support to the valve stems, there is provideda bracket, comprising a cross piece, 17 havinosuitable openings for the valve ste'ins, and a vertical member, 18, at each end of the cross piece, bolted thereto and to the back head of the boiler.

From the foregoing description, it will be obvious that when it is desired to remove the cab from the locomotive, the centre section, 12 may be disconnected from the side sections, by removing the bolts, 12 The cab,

known, of disconnecting the various, con:

nections and valves leading into the cab from the turret prior to removing the cab for repairs, and reconnecting them, when the cab is,

again installed. A further advantage of the improved construction, is that it eliminates the holes heretofore made in the front wall, for the various connections, which holes soon become enlarged in service, permitting undesirable air currents to enter the cab.

I claim as my invention and desire to secure by Letters Patent:

1. A cab turret for locomotives, having a wall formed with a plurality of openings for tapping of connections, said wall being adapted to form a closure for an opening in the front wall of a cab, through which the connections pass.

2. In a cab turret for locomotives, the combination of a wall formed with a plurality of openings for tapping of connections, said wall being adapted to form a closure for an opening in the front wall of a cab, through which the connections pass; and means for attaching the turret to the cab wall in position to close said opening.

8. In a cab turret, the combination of a wall formed with a plurality of openings for tapping of connections, and adapted to form a closure for an opening in the front wall of a cab, through which the connections pass; and a flange, for attaching the turret to the cab wall, in position to close said opening.

. t. In a locomotive, the combination of a cab having a front wall formed with an opening for the passage of connections to the turret; and a turret having a face closing said openin 5. In a locomotive, the combination of a cab, having a front wall formed with an opening; and a turret, closing said opening.

6. In a locomotive, the combination of a cab, having a front wall, formed with an opening; and a turret, attached to said front wall, and closing said opening.

7. In a locomotive, the combination of a cab, having a front wall, formed with an opening; a turret, having a face adapted to close said opening; a flange, for securing the turret to the wall with the face closing said opening; and means for securing the flange to the wall.

8.111 a locomotive, the combination of a cab, having a sheet metal front wall embody ing a detachable section, said section having an opening therethrough; and a turret closing said opening.

9. In alocomotive, the combination of a cab, having a sheet metal front wall, embodying a detachable section, said section having an opening therethrough, for the passage of connections to the turret; a turret, having a wall closing said opening; a
